Cloning Endangered Species Essay

752 words - 4 pages

Cloning of animals is one investment that should be denied funding. Scientists all over the world have been attempting for decades to perfect the cloning process of animals. All the problems that could occur to terminate the cloning process before the clone has a DNA sequence that can be capable of giving life to a creature. The numerous amount of clones that never see adulthood is a waste of technology, time and funding. Cloning to save endangered species sounds like a fantastic idea, but realistically with the technology is not sufficient enough to perform these requests.
Researchers go beyond the normal when it comes to the DNA used to attempt cloning. Two contributors to cloning ...view middle of the document...

As of January 8, 2014 the Genetic Science Learning Center has a success rate that ranges anywhere from one tenth to three percent. This low success rate is caused by many different factors. Some of the factors are based on the nuclear transferring process, some are from the abnormal gene patterns that may occur, and telomeric differences. Abnormal gene patterns involve the nucleus’ being transferred in and the embryos that are naturally in the animal. Although the clones look identical and they share the same DNA sequences, the nucleus does not know how the embryo operates. The telomeric differences are reoccuring DNA sequence shortages. Telomeres are the ends of DNA strands and as the cells divide the telomeres are downsizing. The older the animal the shorter the chromosomes. The life expectancy of clones is unknown to scientists. The unknown life expectancies causes the success rate to be shorter since most of the clones do not live to their adulthood.
Researchers started to question whether or not cloning could help repopulate endangered animals knowing the success rate of domesticated animals. Scientists all over the globe are convinced that through cloning they could possibly save certain species of animals. Carlos Martins an Embrapa researcher from Brazil has two animals that...

These disease are very different to cure, if we use the cloning technology we can change the Gene's DNA order, so we can save lots of people. (Adams, C.J, 2003)One of the huge bonuses of cloning animals is that if you cloned endangered species you could expand their populations immensely. You just need one cell of them, then use cloning technology to save the animal. Take an

Therapeutic vs. Reproductive Cloning

The first successful reproductive cloning occurred with Dolly the sheep and since then horses, mice, cows, dogs, and cats have been successfully cloned. However, there have been no successful attempts to reproductively clone a human being yet. Reproductive cloning has the potential to protect endangered species from

The Ethics of Cloning

This will affirm that cloning is useful because it cures diseases, passes on genes, and repopulates endangered species. In order to have a legitimate argument for the reasoning why cloning is or is not acceptable it is important first to be understand what exactly the topic

Cloning is a Good Thing

1429 words - 6 pages ). Scientists are now trying to get approval to clone humans or at least parts of them (Eccleston, CNN). All of these clonings have led to much criticism and controversy, but the latest attempt at cloning is that of endangered and possibly already extinct species in hopes of preserving them. This short paper will give a brief description of cloning and the pros and cons of preserving endangered and extinct species via means of cloning. Introduction
